The aim of this study was to determine the values of some gravimetric parameters on aboveground parts of wheat. The research was conducted on the Ciprian cultivar. The experimental field was located at the Didactic Station from BUASMV Timisoara. Here the soil can be characterized as a slightly gleized cambic chernozem. The application of fertilizing substances is important due to the fact that it determines qualitative and quantitative changes in crops. Nitrogen is the most used fertilizer globally, due to the fact that it is essential in growth and development. A higher grain yield is assured after the application of ammonium nitrate. For this experiment, five experimental N doses were used: 0, 50, 100, 150 and 200 kg ammonium nitrate ha-1, respectively. The research was realized on the aerial parts of wheat plants. The investigated indices included fresh and dry weights, but also ash content and initial water quantity. The results were analyzed and processed with PAST Software v3. Values lower than 0.05 were considered significant. All the investigated parameters presented the lowest values for N 0 probes and the highest values for N 200 probes, in both periods. Levene's test showed that the values of all parameters for periods 1 and 2 were heterogeneous. Welch F test showed that the data are significantly different.
